Requiring Assistance with Masking and Preserving Colour

h2oqueen wrote on 6/15/2018, 10:54 AM

Hi, sadly the multicoloured font has lost its colour. I have tried both sony vegas mask and also using the properties option trying both, unmatted, dirty and multiply from the project media area. I am currently using unmatted from the video's property option.

Any suggestion as to how I preserve the colours of the font.

The original design was on a black background.

Thank you.

How did you create the original? You need to create an alpha channel.

I deleted the channel, however, I changed the video setting to unmatted (I've reverted it back to none). I originally had the text video channel above the channel featuring the water.

This is not just regular text from Vegas, the text that you see is actually a video.

I have no idea how to make this work. Alpha channel is just default settings I guess?

Yes it certainly looks like you added transparency instead of an alpha mask.

There are masking tutorials on the internet .

Your text video MUST ALSO have its own alpha channel that Vegas recognizes. ..

That video doesn't help me as I am not using Sony Vegas text as per his videos. since, I am using a video that has text displayed in it, my video is a black background, doing the child parent thing doesn't work as his video suggestion. I have no clue how to make this work and its giving me a headache quite frankly.

Both the water and text videos are alpha channels by default.

Regarding the video text it was a Sony Vegas Mask Generator FX that's when all colours were lost I've since deleted it, I have no idea how to preserve the original colours as per displayed in this image.

Thanks for your help any further suggestions perhaps?

I've removed all FX except sharpen on the video 2 channel. As you can see, the text video is black, Sony Vegas Mask Generator, doesn't preserve the multicoloured look.

Because Vegas doesn't support .mov files and after 4 hours of trying this, I found out that the video converted from .mov to .mp4 doesn't support the alpha channel.

 

Why doesn't Sony Vegas support .mov I will never know why :(

Sir, it really doesn't matter. MOV is a container, as is MP4.

One CODEC using the MOV container that supports alpha in Vegas is Avid DNXHD. Its a codec you install. So does Uncompressed, fwiw.

I can't think of common MP4 codecs that support alpha, but several AVI do. If your source video does not already carry a native alpha channel, you will need to create a new source that does, using masking. Go figure.

Beyond that, the video tutorial I posted is entirely relevant, noting only that Vegas text carries it's own alpha channel.

Please experiment, and good luck. The tail doesn't wag the dog in your situation.

The QT animation codec also works very well with an alpha channel. Most compressed formats do not support alpha channels.

Yes, forgot about that one.

RLE encoding is ineffective as a compressor with fast motion, and is not truly lossless due to rounding errors. Wouldn't necessarily suggest it once OP has masked and created the alpha channel for his new source video.

I really think Uncompressed AVI 32 is the best choice for a short intro/outro.

Of course it becomes unrealistic for encoding a full program.

Despite your reservations about the Animation codec, for graphics, I found it anecdotally to be better than any AVI codec. It is clean and has a small footprint.

Musicvid wrote on 6/16/2018, 2:27 PM

It's a good codec, too.

Just that RLE, arguably the oldest form of compression, doesn't hold enough advantage over uncompressed to keep my interest. I think even oldschool Huffy may be smaller for motion video.
